LOCK.

Application filed January 25, 1926. Serial No. 83,518.

My invention relates to looks, more particularly to cylinder locks, although my improvements may be readily applied to other looks as well.

5 p The objects of my invention are: first, to provide a lock having tumblers which may be readily removed for the substituting of others, whereby the combinations of the lock may be readily changed; second, to H) provide a lock of this class which is particularly desirable for hotels, apartment houses or other structures where large number of doors is employed, so that the combinations and keys for the different doors may be easily and periodically changed, if desired; third, to provide a lock assembly having a tumbler assembly adapted to be readily removed from the outside of the door or the like upon which it is mounted for substituting another tumbler assembly without dismounting the lock assembly or removing any other main portion thereof; fourth, to provide a lock structure having a separate tumbler assembly, which, when the lock is mounted in the door or associated member, may be readily removed from the lock structure for substituting another adapted to be operated by a different combination of key bit or an entirely different key, if desired; fifth, to pro vide a look structure of this class in which the cylinder or tumbler casing, when applied to a conventional cylinder lock, may be easily and quickly released from the inside of the door or other member upon which the lock is mounted and removed from the outside of the door or other memher and another quickly and easily substituted; sixth, to provide as a whole a novelly constructed lock, and seventh, to provide a lock structure of this class which is particularly simple and economical of construction, durable, eiiicient, which may be readily changed by any inexperienced person and with a minimum of tools, and a lock structure of this class which will not readily deteriorate or get out of order.

With these and other objects in view, as

will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure l is a side elevational view of my lock structure, showing the same mounted in a door, shown fragmentarily, with the view taken. looking towards the edge of the door, and showing certain parts and portions of the lock structure broken. away and in section to facilitate the illustratiomhig. 2 is a top, view thereof, also showing certain parts and portions of the lock structure broken away and in section to facilitate the illustration; Fig. 3 is a sectional view there of, taken through 3 3 of Fig. 1; Fig. l is a sectional view thereof, taken through 474 of Fig. 2, and Fig. 5 is a partial sectional and partial elevational view thereof, taken on the line 55 of Fig. 2. 1

Like characters of refer to similar parts and portions throughout the several views of the drawings.

The lock shown in the drawings is similar in construction to conventional locks now in use for doors. The lock shown in the drawings is a type of the commonly known cylinder lock and consists essentially of a bolt casing l secured at the inner side and near the free edge of the door D, a bolt 2 reciprocally mounted in the casing 1 and normally held in an outward position by a compression spring 3 positioned around the inner reduced shank end of the bolt 2 between a plate 1 within the casing 1 and a shoulder near the outer end of the bolt 2, a bolt operating plate a secured to the inner end of the shank of the bolt 2, a pair of oppositely disposed bolt operating cams 5 and 6 positioned to engage the normally outer side of the plate l at its opposite edges, a knob turnably mounted in the bolt casing 1 and secured at its inner end to one of the cams 5, a disc 8 turnably mounted in a plate9 secured over the inner side of the casing 1, the disc 8 being secured to the other bolt operating cam 6, a cylinder or tumbler casing 10 extending beyond the outer face of the door 1 and extending with its inner end into a transverse opening D of the door, a plurality of pairs of cylinders or tumblers 11 and 12 mounted in the cylinder or tumbler casing 10, as shown best by dotted lines in Fig. 1, a plurality of com pression springs mounted in the recesses of the cylinders or tumblers, as indicated by 13 in Fig. l, a plug l i adapted to receive the key K and turnably mounted 1 in the cylinder casing and retained in position relatively thereto by means of a retaining member 15, shown in, Figs. 1,. land 3, a motion transmitting bar 16 secured at its one end in the member and inserted with its other end in a slot 8 in thedisc 8, and a ring 17 for supporting and positioning the outer enlarged annular flange 10 of the casing 10 at the normally outer side of the door. y

In the locks now used the ring 17 is normally held in position by the flange 10 of the cylinder or tumbler casing 10, the latter a of which is held in position by a plate at the inner side oi the door. However, in my construction the ring 17 is preferably the edly secured at the outer side of the door by any suitable means, such as by a pair of bolts 19 extending through a plate 18 at the normally inner side of the door and positioned underneath the bolt casing 1. The bolts 19 are screwably secured at their nor mally outer threaded ends in threadedbosses 17, forming a part of the ring 17, as shown best in Figs. 1, 2 and 3. The rin 17 may be positioned relatively to the ho e D of the door I) by means of an annular'iiange,

as shown best in Figs. 1 and 2, and may be non rotatably secured relatively to the door by means of pointed lugs 17*, as shown in F 1. Y

The inner end of the casing 10 is provided preferably with a laterally eiitcnded lug 10", to the extended end of which is secured, by means of a nut 21, the reduced threaded end of. the cylinder casing position ing or securing member 20, which is in the form of a bar, as shown best in Figs. 3, a and This bar may be offset, as shownin Fig. 2, it desired, to meet the interior construction of the bolt casing 1. The. opposite end of the member 520 may be secured in a variety of ways to the casing 1 or the inner side of the door, so that the casing 1 need not be removed. In the structure as shown, the one side or the member 20, facing the free edge of the door, is provided with a plurality of close serrations 101' transverse grooves 20, as shown best in Fig. 2, into which is adapted to be extended a V-shaped or knife edge 9 on the plate 9, as shown best in Fig. 9. The member 20 is preferably made suiticicntly resilient so that the same will normally assume a position away from the if-shaped or knite edge 9, so that the member 20 may be readily inserted into and withdrawn from the opening 9 withoutinterfering with the V-shaped or knife edge, the latter edge forming one side of the opening 9 of the member 9. At the inside of and near the rear end of thebolt casing lis provided a lug 1 against which the normally free end of the member 20 is adapted to be forced. The normally free end 01' the memberQO is secured against the edge 9" of the plate 9 and against the lug 1 01 the casing 1 by means of a set screw 22 accessible and adjustable tromtheend and outside of the casing 1. When the set screw 22 is loosened, the member 20 will spring back wardly, as indicated by dotted lines in Fig.

2, thus permitting the casing 10 to be readily removed without removing the casing 1 or any other essential part of the loclr assembly. The member 20 is also so constructed as to be readilylitted to Various widths of 1 doors, the serrations or transrersegrooves permitting the end of the member 20 to be readily broken oil with a pair of pliers to suit the width of the door.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to belimited to this particular con struction, combination and arrangement nor to the particular type of looks, but desire to include in the scope of my invention, the construction, combination and arrangement of parts and portions as applied to ordinary tumbler locks, locks combined with door:

knobs, as well as other locks now in use,

substantially as set forth in the appended claims.
